To solve force equations (3), multiply the coefficient of friction by weight,
work/distance, and mass by acceleration.
Density equation (1) - mass/volume
equation for the determinate system - ANSWER 2j = m + 3
j = number of joints.
m equals the number of members.
Work equations (3): ANSWER force x distance
Pressure x area x length.
Pressure x Volume of Displaced Liquid
Power equation (3) - ANSWER work/time
Amps^2 (resistance), often known as watts
I(V) or Amps (voltage)
, The ideal mechanical advantage formula (1) is ANSWER load/ideal effort.
Efficiency Formula (1) - ANSWER IMA/AMA
Gear Ratios (2): ANSWER driving gear teeth/driven gear teeth.
=
Driving rotations per minute (RPM) divided by driven rotations per minute (RPM).
Fahrenheit to Celsius conversion - ANSWER F = (9/5)(C)+32
Torsion: ANSWER turning force
Shear is a sliding force that acts in opposite directions.
compression: ANSWER squeezing force, crushing together.
Tension - Pulling apart.
Bending - Compression and Tension Force
Parallel voltage yields the same answer.
parallel resistance - answer 1/R = 1/R(1) + 1/R(2) + 1/R(3)...
Parallel amps - Answer sum.
